FAN AND MOTOR THEREFOR.

SPECIFICATION forming part of Letters Patent No. 497,139, dated May 9,1893.

Application filed August 13, 1892- Serial No. 44:2,96'7. (N0 model.)

To aZZ whom it may concern:

Be it known that we, GEORGE A. SNEOKNER, of San Antonio, in the countyof Bexar and State of Texas, and CHARLES E. ROTH, of New York city, inthe county and State of New York, have invented a new and usefulImprovement in Fans and Motors Therefor, of which the following is afull, clear, and exact description.

Our invention relates to motor-propelled fans, and has for its object toprovide a fan capable of being attached to any support, and especiallyadapted for attachment to a bedstead or other article of furniture.

Another object of the invention is to provide a motor to he used inconjunction with the fan, which motor supplies the propelling power andis exceedingly simple and capable of being manipulated in a convenientmanner.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a rear elevation of the motor and fan. Fig. 2 is a sectionalside elevation thereof. Fig. 3 is a vertical section taken through thebody of the motor, the fan shaft and the drive or spring shaft; and Fig.4: is a detail View of a locking or stop device used in connection withthe fan.

In carrying out the invention the motor A which is of a spring pattern,will be first described. The frame of the motor usually consists of fourpartitions 1O, 11, 12 and 13, the partitions 13 and 10 beingrespectively the rear and front partitions of the frame, while thepartitions 11 and 12 are intermediate ones. These partitions arearranged at suitable distauces apart, and are of the pattern usuallyemployed in the construction of clock-mechanism. Ordinarily the top,back and bottom of the frame is inclosed by a casing 14 of any approvedconstruction, and this casing may be continued over the ends of theframe whenever it is found desirable or necessary to exelude dust, 'orother foreign matter.

Near one end of the frame a hollow shaft 15,is journaled in theintermediate partitions 11 and 12 and in the rear partition 10. Thisshaft extends beyond the inner partition 11, and between the said innerpartition 11 and the next inner partition 12 a spring 16, is coiled, anda like spring 17 is alsopreferably coiled between the partition 11 andthe rear partition 10, and both of these springs are connected with theshaft 15 and are adapted when wound to revolve the shaft; Therefore theshaft 15 maybe properly termed the spring or drive shaft.

The shaft 15, carries at its inner end a large 6 5 gear 18, and thisgear meshes with a pinion 19, fast upon a winding shaft 20, which shaftis journaled in the rear partition 10 and extends inward in direction ofthe next partition 11, as is best shown in Fig.2. Upon this shaft a spurgear 21, is loosely mounted, and the pinion 19, has secured to one ofits side faces a ratchet wheel 22, the ratchet wheel being in closeengagement with the inner face of the spur gear 21. The said spur gearcarries a pawl 23, adapted for constant engagement with the ratchet, andwhen the shaft 20 is turned in one direction by means of its pinion 19,a movement is imparted to the large gear 18 upon the winding shaft insuch manner as to revolve the shaft in a direction to coil or wind upthe springs 16 and 17, and at that time the pawl slips over the ratchetand the loosely mounted spur gear remains stationary. WVhen, however,the large gear 18, is revolved by the action of the springs the windingshaft 20 is turned in a direction the reverse of that in which ittravels when it is used for winding purposes, and at that time theratchet wheel engages with'the pawl 23 go in such a way as to impart arotary movement to the loosely mounted spur gear 21. The pawl 23, inpractice is constructed of such material, or is provided with suchcovering that will render it noiseless when it slips over 5 the ratchetwheel.

Above the winding shaft 20,asecond shaft 24, is journaled between thepartitions 12 and 13, and this shaft carries a pinion 25, which mesheswith the loosely mounted spur wheel 21; and the shaft 24, also carries agear wheel 26, which meshes with a pinion 27 upon a third shaft 28,located above the shaft 24. The shaft 28, has attached thereto alargegear wheel 29, audit in turn meshes with pinion 30, located upon a shaftback of the shaft 28, and this rear shaft carries also a gear wheel 31which is smaller than the gear 29; and the gear wheel 31, is in meshwith a pinion 32, secured to a shaft 33, located above the shaft uponwhich the gears 30 and 31, are secured. The shaft 33 is located at theupper central portion of theframe, and extends beyond its rear side; andupon the outer projecting end of the shaft 33 a balance wheel 34, issecurely fastened, the upper portion whereof is weighted, as illustratedat 35 in Fig. 1, the lower portion being considerably lighter, and thisbalance wheel is provided in one of its spokes with a diametricallylocated slot 36, and within this slot the upper end of a pitman 37, isadjustablyattached, and the lower end of the pitman has pivotallyconnected therewith a crank arm 38.

Power is supplied by the springs 16 and 17 and is transmitted by thepower or drive shaft 15 through the large gear 18 and the train ofgearing embraced between the reference numerals 21 and 33, to the drivenshaft 33 and the balance wheel 34, from which the power is communicatedby means of the pitman 37 and crank arm 38 to the fan.

With reference to the construction of the fan a hollow fixed shaft 39,is passed through all of the partitions in the frame and through thehollow drive shaft 15, the shaft 39 being secured to the frame in anysuitable or approved manner which will prevent it from revolving. Eachend of the hollow inner fixed shaft 39, is closed by a plug 40,preferably screwed to place, and in these end plugs the extremities ofthe fan shaft 41, are journaled, as shown in Fig. 3, the fan shaft beingconsequently located within the fixed shaft, and said fixed hollow shaftextends some distance beyond the front and rearof the frame of themotor, while the crank arm 38, attached to the pitman 37 is carriedthrough an elongated circumferential slot 41 in the fixed shaft near oneof its ends, and is attached to the fan vshaft in such manner as toimpart motion thereto.

A hanger 42, is secured to the fan shaft near theforward end thereof,and this hanger passes out through a circumferential slot 41 produced inthe fixed shaft 39. The hanger 42, is made in two sections, and thesections are universally connected. In Fig. 3 of the drawings thesections are shown united by a ball and socket connection 43, and areheld in the desired position by a set screw 44, forming a part of theconnection. The lower end of the hanger or bracket 42 terminates in asocket 45, and in this socket the shank or handle 46 of any approvedform of fan 47, is

ad justably and removably secured. Thus when the spring is wound arotary movement is imparted to the balance wheel, and a rotaryreciprocating movement is conveyed to the fixed shaft by the pitman 37and crank arm 38, and consequently a rotary reciprocating movement isgiven to the fan or fans connected with the fan shaft.

\Vhen it is desired to stop the fan it is preferably accomplishedthrough the medium of a sleeve 48, which is held to slide upon the fixedtubular shaft 39. The sleeve is provided at one of its ends with twodiametrically-opposite slots 49, and immediately over the connection ofthe hanger with the fan shaft a pin 50 is secured to the tubular fixedshaft. Thus when it is desired to stop the movement of the fan, byslipping the sleeve forward the pin 50 which is stationary, will enterthe upper slot in the sleeve and prevent the sleeve from turning, whilethe hanger may be made to enter the opposite slot in the sleeve and itwill be prevented from moving.

This fan may be applied to any article of furniture, a desk, a bedstead,or the like. In the drawings it is illustrated as being secured to thehead board B of a bedstead, the fixed tubular shaft extending throughthe front of the board, and the motor being attached to the rear facethereof through the medium of lugs 51, or the equivalents thereofattached at the forward portion of the frame, and fastening deviceswhich the lugs are adapted to receive.
